What's New

Current Release: v3.30
Release Date:  May 2022

Newest Features in this Release

  • Add capability for TH to save protocol log file periodically.
  • Add drop down item to File menu “Open Wireshark Log” to allow Wireshark log file to be read into the Test Harness Protocol Analyzer Window for display.
  • Add functions that can be called from Test Plugin interface to save Test Results and Test Execution Results to specified files in addition to the GUI.
  • Implement updated DNP IED Certification Procedure Subset Levels 1, 2, and 3 Version 3.1 from April 2022 not including sections 9 Network and 10 Output Control Events.
  • Create DNP Plugin for simulating and testing Master and Outstation Dual End Point functionality including timer to disconnect after the specified idle time.
  • DNP cleaned up TCL sdnp/mdnp/dnprxcallback commands and help menu for consistency
  • Create SDNP DER Plugin for simulating MESA-DER Outstation.
  • SDNP Add associated point functionality AssocPoint property to Binary and Analog Output Points to cause the associated input point value to change when a control from Master changes the output value.
  • Improve 104 Monitor Mode functionality so it does not complain about CTSTA time stamp because it does not match time on Monitor Mode Test Harness.
  • S101/S104 Add associated control point functionality ControlIOA Property S101 and S104 Monitor Points. This allows more flexibility than ControlPointOffset which applies to the entire sector database. Points which do not have ControlIOA set still use the offset. This must be enabled per sector by setting ControlIOAEnabled to prevent unnecessary processing.

Key Additions to Recent Releases

v3.29

  • Implemented DNP IED Certification Procedure Subset Levels 1, 2, and 3 Version 3.0 from December 2020 including some revisions to the tests through March 2021. This involved additional tests and changes to the Test GUI to allow testing an SDNP device for Level 1, 2, or 3 compliance.
  • Add TCL command tmwserial channel x dtr 1|0 rts 1|0 to control DTR and RTS on COM ports.
  • Added TCL commands i101rxcallback, i102rxcallback, i103rxcallback, i104rxcallback, and mbrxcallback commands for layers link and phys.
  • Allow TCL command “s101db callback” with no specified callback function to unregister a previously registered TCL callback function. Do this for all s10xdb, m10xdb, mdnpdb, sdnpdb, mmbdb, and smbdb functions.
  • Implement a DNP Dual End Point Plugin to configure a Master and/or Outstation and a GUI for sending Enable Unsolicited, Read Command, Generate Event, and Disconnect for demonstration and testing purposes.
  • Increase Maximum supported TX and RX Fragment Sizes for DNP to 65535 for 64 bit Test Harness, remaining at 8K for 32 bit Test Harness install.
  • Provide more complete Monitor Mode diagnostics of DNP control requests even though the controlled DNP point index does not exist in the SDNP Monitor session database.
  • Add support in TCL command mdnpassignclass for sending a DNP request to remove an SDNP point from class 0 as directed by TB2021-001. This includes the ability to create combinations of requests for multiple Class Object Headers and Data Object Headers.
  • For MDNP Secure Authentication V5 show plain text and MAC in the protocol analyzer window when the TH MDNP acts as a DNP3 Authority and creates certification data when using a Symmetric Key Change Method as is done in other situations by the MDNP SCL code.
  • Add SDNP Session configuration counterSizeVarPerPoint, anlginSizeVarPerPoint, and anlgOutSizeVarPerPoint to optionally switch variation in a response to indicate precision on a per point basis even though a specific (ie. non-zero) variation is defaulted or requested.
  • Enhance 103 General Command support for S103 DPI points. Previously only the default points indicated in the IEC-60870-5-103 specification as supporting General Commands had that capability. Added a Property bool GnrlCmdSupported on each S103 DPI point that can be set and viewed in either the TH Data Window or by the TCL command “s103dpi add/set/get gnrlCmd”. This property will also be saved and restored from Test Harness workspaces.
  • More completely implement parsing of responses into TCL arrays for M101 and M104 when datavariable is specified in a command.
